Question

The immediate predecessors of spermatids are ______.

विकल्प

• spermatogonia

• sperm mother cells

• primary spermatocytes

• secondary spermatocytes

Answer 1

The immediate predecessors of spermatids are primary spermatocytes.

Explanation:

In spermatogenesis, diploid spermatogonia (sperm mother cells) first grow and develop into primary spermatocytes. Each primary spermatocyte then undergoes meiosis I to form two haploid secondary spermatocytes. These secondary spermatocytes undergo meiosis II to produce spermatids. Therefore, the immediate predecessors of spermatids are actually the primary spermatocytes because spermatids are formed from secondary spermatocytes, which are derived immediately after the division of primary spermatocytes.
